BL upgrade for which Walkera Heli ?? 

Possibly a 5#10 dual brushless, with outrunners, running on 11.1V 1000MaH Lipos at 30C.  I'd probably cut the cat in half.... 

Seriously, which BL upgrade do you refer.  I just went to Terence's page and only saw the upgrades for the 4#3B and 4G3.

Did you see Walkera now offers the 4#3B and 4G3 in double brushless......OEM.  I'll let them tinker with it for a while, 'cause them seem to change and upgrade their helis faster than I change my socks......

I wish i could find a complete, off the shelf, plug-n-play, double brushless upgrade for my 2.4 Ghz HBFP, with motors, esc and signal converter...... Any ideas Gary ?

Status: offline 		By the way, I wanted to thank you guys (especially Ted and Gary) for all your tips on parts for this little joy of a heli.  I ended up buying the skids and heatsinks for it as recommended and am anxiously awaiting their arrival so that I won't have to worry about burning up the motors regardless of what happens with the BL upgrade.  Out of curiosity, what part of the stock skids did you all experience breaks at, because to be honest my skids appear to be pretty durable and I'm sure you all will agree that they end up taking some hard hits when the owner is trying to learn what the limits to what a coaxial heli can do are (I find that trying to do 3 things at once: turn the tail, bank with the turn and holding forward on the heli causes it to drop like a rock, and I'm still trying to learn to react to this with a full throttle lift to avoid ground contact)

I also ordered myself a spare set of each of the parts you guys have recommended in order to avoid in the field flight time loss, as the majority of the time I fly my 5#10 is an empty rec room at the local Community Center after work hours that has a high ceiling and plenty of empty space.  I have a total of 5 stock batteries at this point, and I noticed as you guys said that the motors run hot after multiple flights in series, so I like to give the 5#10 a rest in between batteries to avoid disaster.  I've also noticed the "defect" you all have experienced with the rudder trim setting as you progress through the battery charge.  I've more gotten used to simply compensating for it with controller inputs than anything else.

I've gotten around 10 flights in so far with the stock batteries, and the worst thing that has happened so far has been due to trying to exceed the capabilities of the chopper and causing it to drop out of the sky and cause a blade strike.  Amazingly enough, the blades got a nice nick in them, but with a little work I managed to straighten out the bent piece and the blades still work fine and don't even cause any vibration!  I do have a spare set of blades ready to go just in case...

Thanks again for all your tips,  I'll be sure to keep you posted on what the results of the brushless upgrade are!

I just looked at Terence's BL upgrade for the 5#10.  Looks interesting.  I assume this is for a 1S setup?  Curious to know what kind of flight times this will result in. 

That's the thing about Walkera's, it is almost a part-time job just to keep up with all the minor (and Major) mods that come out, both from Walkera and others......

I may have to give this upgrade a try.....

Status: offline 		I tried to find more information about the upgrade from Terence directly, but he hasn't tested it yet.  I hope its a 1S solution, as I don't plan on gutting the 5#10 and replacing the 4 in 1 with the Lama one.  I'm too new at this at this point to feel comfortable with that big of a change, besides ordering the Lama 4 in 1 and new batteries would be another $100 or so I'm guessing (I don't have any of these parts sitting around)

Most of the suggestions I've seen regarding making a coaxial more outdoor friendly involve what seem to be easier mods to do: remove the flybar, increase the servo arm throw.  I haven't even tried either of these mods yet.

The kit should be here this week, we'll see how it goes!

If you don't mind me asking, I noticed you finished converting your 5#10 to 2S 7.4V also. What receiver/4-to-1 did you end up using and how does the finished product fare outside? What kind of flight times are you getting?

Hey Ryan,

Charlie


I used the RX-2403 which is from a 5#4Q3 which is basically a Lama/CX in an air wolf fuselage. It's 7.4V setup is exactly what is needed for using those drop in kits.

I have lots of heli's, and while I love flying the 5#10, it is a much better indoor flyer that outside, super smooth and agile. I have flown it outside many times and when there is no wind it is great. However even with adjusting the servo extent pot to max and travel to 130% on TX, it still isn't that fast, compared to some of my other heli's. Now that's just the way I have mine setup because I have better heli's for outside and large indoor spaces to fly the 5#10. It is a light bird after the BL conversion and you can add some little weights and adjust the battery for front CG and I'm sure you could set it up for FFF and it would be great outside.
Power of the 2S setup is off the charts. Most lama drop in kits are made for lama sized gears with 8T pinions. The 5#10 has a much larger gear and many more teeth on pinion.
I get up to 14 minutes of flight on a 900mah 20C battery depending on how hard I push the heli during flight. 12 to 13 minutes is the norm on a 800mah. Higher C rated batteries do make a difference in flight performance with all the BL electronics and RX.

Here's a few pics after the mods. And yes, I know I screwed up the paint job on the canopy.

I have multiple great rooms with lots of space indoors (basketball gym, 30x30 empty room with 12' ceiling) that make for great fun flying indoors, and I have almost no complaints about the 5#10 at this point. I've been trying to decide what to do next as I learn more about the hobby, and continuing to upgrade the 5#10 is one of the two things I've been debating, as most of the comments I've seen have suggested there are better models for adapting for outdoor flight like the Lamas.

The BL kits I ordered should be in later today. I can't wait to get them installed and see how everything flies after!

Status: offline 		Oh so interesting.....great adaptation of the 7.4 4-in-1 with the BL motors. Did you try it with 3.7V? Did it work ??

I have used the OEM 5#10 2401 rx, as well as the upgraded 2410rx and the 2411 rx, for the 3.7V 5G4Q3 Air Wolf (note this is different from the 5#4Q3 which is a 7.4V set-up, as mentioned above). For 3.7V 1S the 2411 is the most powerful rx. The 5#10 OEM uses 130PH motors, but the 5G4Q3 uses the 180 motors, as does the 7.4 V 5#4Q3. I think Walkera discovered that 3.7V was not enough for the 180's on the 5G4Q3, and quickly upgraded the setup to offer the 7.4V solution.....in the 5#4Q3.

I totally agree that higher C rated batteries deliver more power and longer flight times. The stock Walkera 3.7V 1000MaH batteries just barely cut it. I purchased several 3.7V 1000MaH 20C batteries on-line. I have seen a bit of better overall performance on the 5#10 using these batteries, as well as longer flight times. However, they make a WORLD of difference on the higher current-draw 3.7V 1S 4G1B, which uses a 370SD main motor. The Walkera 53 series co-ax's (53-1, 53-8, 53Q3 and 53Q3 with the "D" mod, which offers a power tap for lighting) heli's are also 7.4V. These rx's may also offer a BL 4-in-1 solution, if you want to stick to Walkera 4-in-1's.

As mentioned above, the 2403 7.4V 4-in-1 used by Crushalot may be the best overall solution, as it was designed for the 130/180 types of motors.

You CAN NOT use 7.4V 2S li-po's on the stock 5#10 4-in-1's - 2401, 2410, or the 2411) as this will quickly fry your 4-in-1 and servos....

So many possibilities....... Ted

Status: offline 		Still waiting on the arrival of the drop in solution from Terence at CJ, it should be here later today and I'm sure I will be installing it before the nights over.

I've just been giving the 7.4V upgrade thought because the more and more I read, the more likely it seems that what is going to show up today is in fact a 7.4V set of BL motors and ESCs. If what shows up is in fact that, then I have no choice but to persue the 7.4V upgrade (either I wasted $70 on the BL kit, or I spend a bit more and get the parts I need to complete the 7.4V upgrade)

Status: offline 		The BL kit from Terence is for the 1S stock setup of the 5#10 and should work ok because of the gear ratio of the 5#10. It won't have the flight times or power of a 2S setup, but it should be a nice upgrade over stock motors. AEO did a bit of testing on this kit and in fact delayed releasing it due to something they discovered during testing, so I am sure it will work fine.

I couldn't even try to hook up the Lama BL kit to the old 4in1 because the 5A ESC's in the kit are for 2S or 3S and pretty sure those won't run on 1S. That is one of the things they had to change from testing, to make the ESC 1S capable. (AEO makes the Lama kit as well and uses pretty much the same components in most of there BL kits, just configured for the needs of any particular kit)

I'm interested to see how the 5#10 kit performs. I will try to make some flight video's of my 5#10 this weekend.

They also have them here along with all the other AEO BL kits like for 380 co-ax's and micro'r like the 5G6-1 here:

Both are in China but both are quality vendors.

Status: offline 		Well, I got the kit from Terence today as expected. I just finished getting everything installed, but unfortunately one of the ESC's appears to be malfunctioning. Everything lights up as it should, i.e. both ESCs LEDs light up when power is connected, and both LEDs blink in rapid succession directly proportional to how high I move the throttle, but only one motor turns (the bottom one). I verified that it isn't a bad motor, as connecting the known working ESC to either motor results in spinning, and I verified there is nothing wrong with either channel on the 4-to-1 as connecting the ESC to either channel results in spinning as well.

I remember reading somewhere on here about how to program the ESCs and am thinking maybe I have to do something to get it to work right, but maybe its just a broken one :/ Does anyone have any suggestions or should I just wait to hear back from Terence?

Status: offline 		If you disconnect the motor from the working ESC and then power up, does the non working motor make any noise to confirm the ESC is ready? Do you see any broken joints where the leads are soldered onto the board? Also because this is a 1S setup powering 2 ESC's and 1 RX and 2 C10 motors when working, are you using a good, fully charged battery?

I also was going to write AEO and ask them about the programming sequences for there ESC's. It will be a pain somewhat in the kit, because you have to give power to only one ESC at a time to program and since the kits are Y'ed together, you will have to cut power cable to one ESC and then reattach.
However if you don't mind the solder work, the programming is easy. Just need the programming codes from AEO.

Ryan

PS- I'm sure Terence will help you out and get this resolved one way or another, but that might mean waiting for a replacement.

Status: offline 		Neither of the ESCs make any noise. They just have an LED onboard that lights up solid when I power up, and blink at a rate proportional to the throttle when I throttle up. Neither of the motors give any kind of confirmation to let you know that they are "ready".

I checked the connections and solder joints, and I noticed that the wires connected to the bad ESCs outs (the ones that go to the BL motor) were only soldered to the bottom 3 of 4 poles on the IC they are soldered to. The ones on the working ESC were soldered to all 4 of the poles on that side of the IC. I figured that might be the problem, so I soldered the out wires to all of the poles on all 3 ICs and tried it again. Still nothing.

I already let Terence know about all of this as well, and he is probably getting it touch with AEORC to sort it all out.

Incidentally, it doesn't feel like even the working ESC/BL motor spins all that fast. I've been running all of the tests with the new 1200mAh batteries that I ordered as well, and still at full throttle, I'd swear that the stock motors with stock batteries were alot faster but I could be wrong. I'm also at a disadvantage to judge it since I'm only able to work with one motor at a time right now, effectively half of the thrust I'd have normally.

So my next mission is to get all of the parts so that I can try to convert it to a 2S. Gonna go through this thread and see if I can figure out what all I need to get it done and then decide if its worth it :P

Status: offline 		That funny, because the early photo's I saw of the kit being tested by AEO were 2S setups. So when the kit came out I ask terence if they kept the 2S config of if they changed it to run on stock 1S. He thought it was 1S.

So the AEO Esky Lama drop in kits from hobbycity or elemodels work fine for the motors and electronics - $ 70
You will have to remove the stock pinions and install them on the motors. The biggest issue in the 2S conversion is to make a battery tray to accommodate the larger 2S battery.
I used a Lama battery tray and skids screwed into the 5#10 landing gear braces with the sides cut off (See pics from a few posts back) $10
Finally you will need a 7.4V RX. The walkera RX-2403 works great - $35

I have an extra 2403 I am selling for $30 and I also have a extra Lama BL kit from hobbycity - $60 PM if interested.

Good luck

I have a newer walkera 5#10 heli which I really like alot. Recently my heli will not rise higher then about two feet. I have changed the two plastic gears, battery and 2 motors and still my heli is not flying above two feet or so.

What can I try to fix this problem??

Thanks again for any help!

Any progress yet on your brushless system with 2S setup? I ordered the same setup and am awaiting the shipment myself.

I just got a 5#10 this past Friday and having a ball so far.

Thanks everyone

I have a used 5#10 on the way so that I don't have to rip apart my favorite heli, a used receiver from Crushalot, and a new pair of larger more accomodating landing skids enroute, so the project will be underway this week. Now I still need to buy a balancer/battery charger, some 800mAh lipos, and some micro deans connectors to change the battery connector on the receiver (its what the 2S 7.4V 800mAh batteries I currently have are fitted with) and all should be well. I'll let you know how it works out!
